<P>PROBLEM TO BE SOLVED: To provide an instrument module which prevents the influence of noise such as static electricity generating on a display panel and receives a short-wavelength radio wave by an antenna device. <P>SOLUTION: The instrument module comprises a circuit board 15 on which a control circuit element 17 and a receiving circuit element 18 are installed, the antenna device 5 in which first and second electrode plates 25, 26 are provided in a holding member 24 so that they face each other across a predetermined gap and which is attached to a position in the vicinity of the receiving circuit element 18, a display panel 13 which is supported so that it is electrically connected to the circuit board 15 through an interconnector 19, and a shield plate 20 which is arranged between the circuit board 15 and the display panel 13 to cover the control circuit element 17 and the receiving circuit element 18. Even when noise such as static electricity occurs through the drive of the display panel 13, the control circuit element 17, the receiving circuit element 18, and the circuit board 15 are protected from the influence of the noise owing to the shield plate 20, thereby allowing to receive a short-wavelength radio wave with high sensitivity by the antenna device 5. <P>COPYRIGHT: (C)2008,JPO&INPIT |
